Default Drilling Wing Doubler for BSPQ-5 Rivets

Just curious...but Van's just issued this plans change:

"Page 17-02 Rev 2: In Step 4, changed “Final-Drill #22” to “Final-Drill #20.” "

That was a while ago for me and for the life of me I can remember what I did. I checked my drill bit inventory and cant find a #22 so my guess is that I used a 5/32 bit because it was so close to a #22 bit... .156" vs. .157"

My guess is also that the change is to allow for a larger hole so that the rivet properly sets (expands). #20 is about .161" dia.

A BSPQ-5 rivet is .157". I don't remember having any problems inserting these rivets. Perhaps they where already punched pretty close to where they needed to be (?).

Anyone else paranoid about this or...remember what you did?
